I-405/Northeast 132nd Street Interchange Project

Project overview

WSDOT and design-build contractor Graham Contracting, Ltd. will construct a new on-ramp to northbound I-405 and a new off-ramp from southbound I-405 at Northeast 132nd Street in Kirkland. This type of interchange is known as a half-diamond. After this project is complete, travelers will have the option to access I-405 at Northeast 132nd Street, rather than traveling to the heavily congested Northeast 124th Street or Northeast 160th Street interchanges. The project design includes roundabouts at the intersections of the new ramps to better manage traffic flow. The design also includes sidewalk and bicycle lane enhancements along both sides of Northeast 132nd Street and along connecting streets in the project vicinity. The project also improves drainage, water quality and fish barrier correction to create over a half mile of new upstream fish habitat.

What to expect

Paving work on local streets begins March 25

Crews will complete paving work throughout the project area from Monday, March 25, through Friday, March 29. Work areas include city roads throughout the project area and will vary as the work progresses. Below is a summary of what to expect:

  • Monday, March 25, through Tuesday, March 26: Crews will complete daytime paving work on 116th Place Northeast and 116th Avenue Northeast.
  • Wednesday, March 27, through Friday, March 29: Crews will complete nighttime paving work on additional city roads throughout the site. This work will take place at night to limit impacts to the traveling public and allow crews to safely complete paving operations outside of peak travel periods.

During all work activities, vehicular and pedestrian traffic will be maintained. Crews will use temporary single-lane closures with flaggers to allow traffic to travel safely in the area. Please plan ahead for increased travel times and expect periods of increased work noise. This work is weather-dependent and subject to change.

Completing the paving work is one of the final steps toward allowing crews to complete the I-405/Northeast 132nd Street Interchange Project by Spring 2024.

The project includes roundabouts at the intersections of the new ramps and Northeast 132nd Street.
